Proudly American-Made Marine Hardware Since 1994
For over 30 years, Hillside Castings LLC has supplied durable, American-made aluminum parts for boat builders, dock manufacturers, and marine professionals across North America. What started on a hillside in Hatfield, Arkansas, has grown into a trusted, family-run foundry known for quality, honesty, and fast turnaround.
Hillside Castings LLC continues the tradition of craftsmanship and personal service that made the company what it is today. Every product is poured, shaped, and inspected by hand in our Arkansas foundry. Nothing is outsourced, and every piece that leaves our shop reflects the pride we take in doing things right.
At Hillside Castings LLC, we are focused on providing the highest quality cast aluminum hardware for your maritime needs. We use only premium grade A356.2 aluminum, gravity poured into permanent cast iron molds. While our primary products are marine hardware, we are happy to quote custom cast aluminum products and parts.
Made the Right Way, Right Here in America
We’re proud to do things a little differently. Here’s why our customers keep coming back:
How We Work
Our casting process combines traditional craftsmanship with modern consistency.
We melt certified aluminum ingots, gravity-pour into permanent molds, and hand-finish each piece before it leaves the shop.
The result? Smooth, strong, and dependable hardware that’s easy to weld and built to last for years of service.
